Our present invention has to do with a new and novel container for a spool of yarn.

One object of our invention is to produce a container within which yarn wound upon spools may be dried so that even shrinkage results.

Another object of our inventionas to pro vide such a container that the drying of t e yarn is so controlled that the dryingwill lm wa s take place in some specified dlrection.

ther objects will become apparent from a reading of the .followin specification, and a study of the attached rawing, in which: Figure 1 is a longitudinal cross-sectlonal 15 view of our new container in place upon a 2o yarn, threads, etc., by any of the well-known processes wherein the filaments, etc. are wetspun, they are collected directly upon per forated spools on a so-called spinning machine. These spools, after the necessary wetdesulphurizing, etc.), are dried. This drying is accomplis'hed by placing the spools upon carry ng means, and transporting them into a drier. Here, air is circulated at some veloclty, and

so usually at a relatively high temperature, so

that the outside and the inside of the spools tend to dry at the same time. Thus the yarn cake or body, which is wound u on the perforated spool, dries from both irections towards the middle. This resultsin a yarn body which is perfectly dried, onthe'outside and inside, but imperfectly dried in the middle. The resulting yarn has a very un- I 1 evenshrinkagea This uneven shrinkage'has 40'. anobjectionable efiect on the quahtles of the yarn,- and efiects, for example,'the even drying of the same.

Through the use of our new container,

however, it is possible to obtain an even shrinks. of the yarn body, and correspond- 1 ingpdesuablecharacteristics resultmgtherefrom.

As shown the drawing, the new container is used in conjunctionwith a per-' iorated spool l upon which the" wet yarn even shrinkagdresultm body 2 is wound. The container proper 3' has a cover-portion 4. Gaskets 5, 5 are provided', which act to hermetically seal the container against the spool. Thiscontainer may i be made of any rigid material which will not be acted upon by the liquids with which the yarn body is wet. These materials ma be, for example, bakelite, stainless stee aluminum, hard rubber,etc. The cover 4 is equipped with a gasket 7, which completes the seal. The cover 4 is provided with an orifice 8 terminating in inwardly projecting rims which act to position the covers u on the spool ends. 'The inwardly projecting runs 9, 9 may be of such a' length that they will guide the spool of yarn into the containers without allowing the delicate yarn to come in direct contact with the container.

In operation, the yarn is wound upon the perforated spools in the customary manner,

and the container placed therearound. After the covers are sealed in place by means of the gaskets, the spool, in the container, is placed in the drymg room in the ordinary manner. Because t e outside of the spool is sealed, the'circulat-ion of air is through the interior of the spool only and, as a result, the inside of the yarn body dries first. Thus all the moisture in the am body is removed through the inside of t e spool; The spools are then uncovered and placed on a twisting machine where the filaments or yarn is wound loosely upon a similar spool, and twisted. In this way, the yarn formerly on the outside is now on the inside. The-resultin body is rewet, the s ools are again placed in the contamers, an the same drying operation repeated. Asa resultra yarn with ever f. Although some" departures from the -exactstructure disclosed, the fundamental operations of the container and as- I keted covers sealed with the gaskets against the s 001 should be maintained.

at 'we claim is: 1. In 'a-container, in combination, a cylindrical wallortion, an inturned projection v h at one end t ereof, a gasket associated with the said pro ection, a cover portion, said coverportmn being open-centered and chanmay be made nel-shaped, and adapted to engage the other end of the cylindrical wall portion forming a fluid tight seal therewith.

- 2. A container and closure therefore com- I prising a cylindrical container wall inturned and upturned to form a containing means, and an open-centered channel-like closure adapted to form a fluid tight seal with the top end of said container.

" 3. In combination a cylindrical wall, inturned and upturned end thereof, a gasket at the junction of the inturned and upturned ortions, a beaded edge at the top of the said cylindrical portion, and a closure, comprising aflat strip, 3

the inner side being downturnedv and the outer in-and down turned, a gasket on the inside of the downturned portion and on the outside of the said in-and downturned portion.

4. In combination, a container and closure therefor, and a spool to be held therein, comprisin 'a cylindrical wall inturned and upturne holding one end of the spool, and an 0 encentered channel like closure adapted to orm a fluid the top of the container.

5. In combination, a container and closure therefor, and a spool to be held therein said iglool having wound thereupon a body of ead, comprising a cylindrical wall positioned so that no contactis made with said body of thread, and which is inturned and upturned to form a containing means, and holding one end of the spool, and an 0 encentered channel like closure adapted to drm a fluid ti ht seal with the other end of the spool an thetop of the container.

6. In combination, a spool with filaments wound thereon, and a container comprising a rigid wall portion spaced from the surface of the filaments, a pro'ection at one end of the said wall portion a apted to form a fluid tight seal with one end of the spool, and a closure plortion adapted to close the upper end of t e container'between the other end of the spool and'wall portion, forming a fluid-tight seal with both elements.

In testimony whereof we aflix our signa- RICHARD ELSSN'ER. RALPH H. CARTER.
